Hydrolyzed Horse Placenta Extract
INCI: Hydrolyzed Horse Placenta Extract
A protein-rich extract that may help hydrate and support skin repair, but human studies are limited and ethical sourcing is a concern.
In plain English
This ingredient is made from horse placenta that has been broken down into smaller proteins so your skin can absorb them more easily. It's thought to help moisturize and support the skin's natural repair process, but there isn't a lot of strong scientific proof yet. Some people choose to avoid it due to ethical concerns about animal-derived ingredients.

Hydrolyzed Horse Placenta Extract is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Hydrolyzed Horse Placenta Extract.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
Hydrolyzed Horse Placenta Extract is a processed form of horse placenta, where the proteins are broken down into smaller peptides and amino acids through hydrolysis. This makes them more absorbable by the skin.
How it works
In skincare, the peptides and amino acids from the hydrolyzed placenta act as humectants, drawing moisture into the skin. They may also provide building blocks that support the skin's natural repair and collagen production, though the exact mechanisms are not fully proven in humans.
Pros
Moisture-boosting
The hydrolyzed proteins act as humectants, helping to attract and hold moisture in the skin, which can improve hydration and plumpness.
Potential repair support
Amino acids and peptides may provide building blocks that support the skin's natural repair processes, though more research is needed.
Cons and cautions
Limited evidence
Most benefits are based on anecdotal reports or small studies; large-scale human trials are lacking, so effectiveness is not well-established.
Ethical concerns
The ingredient is animal-derived, which may be a concern for those seeking cruelty-free or vegan skincare options.
Best for
- People looking for extra hydration
- Those interested in protein-rich skincare
Use caution if
- Vegans and vegetarians
- Individuals with known allergies to animal-derived proteins
Usage tips
Safety summary
Hydrolyzed Horse Placenta Extract is considered safe for topical use in cosmetics at typical concentrations. Allergic reactions are rare but possible, especially in those with sensitivities to animal proteins. Ethical concerns about animal sourcing are the main drawback.
Research notes
Evidence is primarily anecdotal or from small studies. Some research suggests hydrolyzed placental proteins can improve skin hydration and elasticity, but large-scale human trials are needed to confirm these effects.
Common label clues
- Typical concentration
- 0.5% to 5% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the US and EU, but not specifically approved for medical claims.
- Common uses
- Anti-aging creams, Serums, Moisturizers, Eye creams
- Environmental note
- Sourcing from horses raises ethical and sustainability questions; look for brands that disclose humane and transparent sourcing practices.
Good to know
- Hydrolysis breaks down large proteins into smaller peptides, making them more absorbable by the skin.
- This ingredient is sometimes marketed as a 'placental extract' in anti-aging products.
